The table below shows data from a random survey of juice preferences.


Types of Juice Number of People

Orange --------- 75

Apple --------- 110

Kale ---------- 65







Part A


Complete the probability model by listing the probabilities for each event based on the data recorded in the table.



S = { O, A, K}

Events ------------ Probabilities

Prefer orange ----- P(orange)= __ %

Prefer apple ------ P(apple)= __ %

Prefer kale -------- P(kale)= __ %



Part B

Based on the data, estimate how many of 400 juice drinkers will prefer apple juice.


The number of juice drinkers who prefer apple juice is __

Answers

Answer:

Part A

30

44

26

Part B

176

Step-by-step explanation:

Total: 65+110+75 = 250

P(O) = 75/250 × 100 = 30%

P(A) = 110/250 × 100 = 44%

P(K) = 65/250 × 100 = 26%

Apple juice:

44% of 400

Consider a single spin of the spinner.


Which events are mutually exclusive? Choose all that apply.


a

landing on an unshaded sector and landing on a number less than 2

b

landing on a shaded sector and landing on a 3

c

landing on an unshaded portion and landing on an odd number

d

landing on a shaded sector and landing on an even number

e

landing on a shaded sector and landing on a number greater than 3

Answers

The question is incomplete

Find attached to the question, the appropriate diagram

Answer:

a) landing on an unshaded sector and landing on a number less than 2

b) landing on a shaded sector and landing on a 3

Step-by-step explanation:

Mutually exclusive events are two events that can occur separately on their own but they cannot occur together or at the same time.

The options given are explained below:

We have two shaded sectors: 1 and 4

We have two unshaded sectors : 2 and 3

a) landing on an unshaded sector and landing on a number less than 2

Looking at option a, we find out that it is possible for the spinners to land on an unshaded sector separately likewise on a number less than 2 but it cannot land on an unshaded sector AND and number less than 2 because looking at the spinner, the numbers on the unshaded sectors are 2 ( is equal to two) and 3 ( which is above 2).

Therefore this option is mutually exclusive and correct.

b) landing on a shaded sector and landing on a 3

It is possible to land on a shaded sector likewise it is possible to land on a 3 but it is not possible to land on a shaded sector and land on a 3 at the same time.

This is because, the number on the shaded sector is 1 and 4 and the number on the unshaded sector is 2 and 3, we have only one spinner so the spinner can only land on one sector at a time.

Therefore, Option b is a mutually exclusive event and it is a correct option.

c) landing on an unshaded portion and landing on an odd number

The unshaded portion on the spinner has number 2 and 3 on them, therefore it is possible to land on an unshaded portion and odd number which is 3 at the same time.

Option c is not a mutually inclusive event and it is wrong.

d) landing on a shaded sector and landing on an even number

The shaded sector on the spinner has number 1 and 4 on them, therefore it is possible to land on an shaded sector and even number which is 4 at the same time.

Option d is not a mutually inclusive event and it is wrong.

e)landing on a shaded sector and landing on a number greater than 3

The shaded sector on the spinner has number 1 and 4 on them, therefore it is possible to land on an shaded sector and a number greater than 3 which is 4 at the same time.

Option e is not a mutually inclusive event and it is wrong.

Therefore, option a and option b are mutually exclusive events and they are correct.

Answer:

a.  landing on an unshaded sector and landing on a number less than 2

e  landing on a shaded sector and landing on a number greater than 3

Step-by-step explanation:

Two events ; for example events A and B are said to be mutually exclusive , if they cannot both occur simultaneously.In set theoretical notation , we say that the two sets A and B are disjoint set.

i.e

A ∩ B = ∅

Pr (A ∩ B) = 0

The intersection of A and B is an empty set and as such there is no intersection.

From the given options; option a and e are correct because ;

a.

landing on an unshaded sector and landing on a number less than 2

Landing on an unshaded portion would 2 or 3.

Landing on a number less than 2 would be 1.

There is no intersection and as such these events are mutually exclusive.

e.

landing on a shaded sector and landing on a number greater than 3

Landing on a shaded portion would be 1 or 4.

Landing on a number greater than 3 would be just 4.

The intersection of both events will be an empty set (∅)

As such these events are not mutually exclusive.

SOLVE FOR VOLUME

Answers

Answer:

volume = area of triangle * height = 12.124355653*14/2    *    20 = 1697.40 m3

Step-by-step explanation:

the triangle is equilateral triangle ->

a^2 = 14^2 - 7^2 = 147

-> a = 12.124355653

volume = area of triangle * height = 12.124355653*14/2    *    20 = 1697.40 m3

Answer:

[tex]196meters^2[/tex]

Step-by-step explanation:

The formula for the area of a triangle is : [tex]\frac{base*height}{2}[/tex]

To work this out you would first have to work out the area of the triangle. You can do this by multiplying the base of 14 by the height of 14, this gives you 196.

The next step is to divide the answer of 196 by 2, this gives you 98. This is because the formula is the same as that for the area of a square and that a triangle would be half of a square with the same dimensions.

The final step is to multiply 98 by the length  of 20, this gives you 1960 meters cubed.

1) Multiply 14 by 14.

[tex]14*14=196[/tex]

2) Divide 196 by 2.

[tex]196/2=98[/tex]

3) Multiply 98 by 20.

[tex]98*20=196meters^2[/tex]

The probability of selection even number at random is 2/5.

What is probability?

Probability is possibility that deals with "occurrence of random event at a time".

According to the question,

From the numbers 1,2,3,4,5

Number of sample space = 5

Number of even numbers = 2

Probability of an event = [tex]\frac{sum of favorable events}{Total number of events}[/tex]

In order to find probability of selection even number at random:

=2/5.

Hence, the probability of selection even number at random is 2/5.

Answers

Answer:

Step-by-step explanation:

factor out 100

100[7 + (4 * 11) + (8 * 110)]

100[7 + 44 + 880]

100 (931)

= 93100

standard form is 9.31 * 10^4

The standard form for the number (7×100)+(4×1100)+(8×11,000) is,  9.31×10⁴

What is the standard form of a number?

The standard form for a number is a method by which we write number in a format like  b×10ˣ. The value of b should be in between 0 to 10.

Given Number,

⇒ (7×100)+(4×1100)+(8×11,000)

   by taking 100 common from all the three terms,

⇒  100[ 7+ (4×11) + (8×110) ]

⇒  100[7+44+880]

⇒   100×931

⇒    9.31×10⁴
